"The TeraDisc is made of a material which is highly responsive to two-photon writing and reading. This allows us to write anywhere in that we can focus a red laser onto the disc, e.g. multiple layers," Dr. Erez told TFOT.info. "However, many other properties of the material have to be optimised to allow this to work properly. Especially the written points, and written layers have to remain transparent after writing, without which it would be very difficult for the reading process to see the 200th layer through 199 written, non-transparent layers. "When a red laser is focused to a small spot inside the TeraDisc, we can choose if we probe the state of this material (reading , low power) or alter it (writing at higher power). This is very similar to the way a regular CDR works, except for the fact that this is now done in 3D," she said. It's hard to imagine that a disc format not invented by one of the world's big technology firms could become a future industry standard. But it's... See less

M. Sheeran. Hardware Design and Functional Programming: a Perfect Match. Invited paper. Has now appeared in Journal of Universal Computer Science, Special issue devoted to the Brazilian Symposium on Programming Languages, 2005. This is a slightly odd paper that explains why I am still as fascinated by the combination of functional programming and hardware design as I have ever been. It includes some looking back over my own research and that of others, and contains 60 references. It explains what kinds of research I am doing now, and why, and also presents some neat new results about parallel prefix circuits. It ends by posing lots of hard questions that we need to answer if we are to be able to design and verify circuits successfully in the future. Please note that copyright is held by JUCS. You can get the final version of the paper (in pdf) if your library has access to JUCS. See less

Mathematical software can be very expensive. Programs like Mathematica, Maple and Matlab are incredibly powerful, flexible and usually well documented and supported. Their price tags however are a big let down for many people, even if there are cheap, crippled versions available for educational purposes (if you are a student or a teacher). The secondary disadvantages are those caused by the fact that such programs are proprietary. This can also affect or limit a “sharing oriented” environment like the academic and research fields. In this short article I propose well known programs that will give you a lot of flexibility and math crunching fun. All of them have advantages and drawbacks and none of them can be considered perfect or infallible, but I consider them some of the best available today in their respective categories. They are rather general purpose softwares, but there are plenty of other specialized open source programs if you have specific needs. I’ve chosen one program for... See less

Using a form of cross scripting, it becomes easy to steal a GMail user’s contact list if they visit a certain type of website. The only condition is you have to be logged in to GMail at the time of the attack. GMail is setup to store your contact list in javascript files, which is the core problem. If you log into your GMail account, and click here, you’ll see your contact’s details, along with their email. I've tried the hack on IE7, Opera, and Firefox; it appears to be working on all three. To see a demonstration of the attack, login to your GMail account and go to this website. I don’t know for sure if the list is being saved or not, so browse at your own risk. According to the website they aren’t saving the data. Something worth noting is that the email it claims is yours, is never yours. I tried it on two different emails, and it failed both times. However both times it listed the address I get email from most as mine. Also in the image I've included, shows 23 contacts when it did... See less

Posted by Carlton Bale on November 15th, 2006 I’ve read various articles debating the importance of the 1080p. I want to set the record straight once and for all: if you are serious about properly setting up your viewing room, you will definitely benefit from 1080p (and even 1440p.) Why? Because the 1080p resolution is the first to deliver enough detail to your eyeball when you are seated at the proper distance from the screen. But don’t just take my word for it: read on for the proof. There are a few obvious factors to being able to detect resolution differences: the resolution of the screen, the size of the screen, and the viewing distance. To be able to detect differences between resolutions, the screen must be large enough and you must sit close enough. So the question becomes “How do I know if need a higher resolution or not?”. Here is your answer. Based on the resolving ability of the human eye (with 20/20 vision it is possible to resolve 1/60th of a degree of an arc), it is... See less

morpheus83 writes "Sharp Corporation and Sharp Laboratories of Europe, Ltd. (SLE) have developed the Triple Directional Viewing LCD, a display that controls the viewing angle so that the display can show different images from the left, right, and center simultaneously. Using proprietary parallax barrier on a standard TFT LCD, the screen splits light in three directions — left, right, and center — and displays three separate images on the same screen at the same time. So connect three computers to the LCD and from the center you see Windows, Linux from the left and MacOS from the right." See less

Photo by Gregory Lee Here’s a quick tip for those of us lucky enough to be taking a trip in an aeroplane and wanting to get the classic ‘out of the window shot’ that often is featured early in a travel photo album. One common mistake that people make with taking this shots is to put their camera’s lens right up against the glass of the window in the hope that it will help cut down on reflections and in the hope that it will steady their shot. While it might help a little with reflections it generally does anything but steady the shot and will often usually increase camera shake’ due to the vibrations of the plane. A better strategy, if you’re using a DSLR with a fitted lens, is to attach a lens hood to your lens and get in as close as you can to the window without actually touching it. Alternatively, use your free hand to cup around the lens as much as you can to shield it from reflections. Of course for high quality aerial shots you’ll want to shoot out an open window from an...

How much memory is enough? That's a question that's bothered me -- and thousands of other computer users -- for years. And so far, I haven't seen too many answers that have really satisfied me. It's especially important because, while the type of memory -- whether it be DDR, DDR2, or some other -- is locked in stone by which motherboard and processor your system works with, you get to choose the amount of memory that comes with a new machine (and add to it later). However, it's not easy to figure out how much is enough -- computer memory is situational. What you're doing and the software you're using to do it are the deciding factors in determining the optimal memory size for your computer -- and they can change from PC to PC. For example, according to Microsoft, all you need to run the Professional version of its Windows XP operating system is "128 megabytes (MB) of RAM or higher recommended (64 MB minimum supported; may limit performance and some features)." There's a minimum... See less

Unload your camera and, using Photoshop, resize your photographs (try width or height of 800 pixels). It's tedious to do this manually for each photo; so to expedite the process, record the resizing and saving of one photo as a new Photoshop Action. Then go to File > Automate > Batch to select the new action and apply it to your entire folder of Panography photos (this is also where you can select photomerge and have photoshop do all the work). * Create a fairly large new RGB canvas to work on. If it turns out the canvas is too small, you can always add some space later (Image > Canvas). Copy the new 800px versions of your images into your canvas--5 to 10 images at a time ought to be manageable. * Set the opacity of each photo to about 50%. Using the Transform function (Ctrl/Apple+T), start rotating each photo to fit the ones next to it. Be careful to make sure you're rotating (you should see a curved arrow tool when you're near a corner) and not skewing the photographs. Now go photo... See less

This is a supplementary document for Chapter 1 from my book Mac OS X Internals: A Systems Approach (see Amazon.com page). A subset (about 30%) of this document appears in the book as the first chapter with the title "Origins of Mac OS X". The document is titled "A Technical History of Apple's Operating Systems". Whereas the book's abridged version covers the history of Mac OS X, this document's coverage is considerably broader. It encompasses not only Mac OS X and its relevant ancestors, but the various operating systems that Apple has dabbled with since the company's inception, and many systems that were direct or indirect sources of inspiration. This was the first chapter I wrote for the book. It was particularly difficult to write in terms of the time and other resources required in researching the material. I often had to find and scavenge ancient documentation, software, and hardware (all actual screenshots shown in this document were captured first hand.) However, I couldn't... See less

Geek activism has not taken off yet, but it should. With the gamers recognizing the need for a louder voice, EFF gaining momentum and Linux taking on the mainstream on the one hand and recent severe losses in privacy, freedom of speech and intellectual property rights on the other, now seems to be the best time to rally around the cause. Geeks are not known to be political or highly vocal (outside of our own circles)- this must change if we want things to improve. So here is my list of things people of all shapes, sizes and sides of the debate need to know. Some of these are obvious, others may not be meant for you. But hopefully, some of these will inspire you to do the right thing and others will help you frame the next discussion, debate or argument you have on these topics. See less

Feedback control is the basic mechanism by which systems, whether mechanical, electrical, or biological, maintain their equilibrium or homeostasis. In the higher life forms, the conditions under which life can continue are quite narrow. A change in body temperature of half a degree is generally a sign of illness. The homeostasis of the body is maintained through the use of feedback control [Wiener 1948]. A primary contribution of C.R. Darwin during the last century was the theory that feedback over long time periods is responsible for the evolution of species. In 1931 V. Volterra explained the balance between two populations of fish in a closed pond using the theory of feedback. Feedback control may be defined as the use of difference signals, determined by comparing the actual values of system variables to their desired values, as a means of controlling a system. An everyday example of a feedback control system is an automobile speed control, which uses the difference between the... See less

LucasArts themselves also parodied the THX slogan "The Audience Is Listening" in The Curse of Monkey Island, as the game starts up with a choir of chittering monkeys which grows bigger and louder in the spirit of Deep Note, and ends with the slogan "CMI — The Monkeys are Listening". After the opening logos in Bug Too! for the Sega Saturn, a similar version of the THX jingle is heard as we see Bug vacuuming his floor, plus it becomes "BHX — The Bugs are Listening." The Asia song "Countdown to Zero" from the 1985 album Astra begins with an effect similar to "Deep Note." Rapper Dr. Dre was sued in 2000 by Lucasfilm, then-owner of THX, for using an unauthorized cover of "Deep Note" on his 2001 album. [2] See less
